Learning php. Set-up IIS7 on my local Win 7 computer. Accessing data from an Oracle database. Dreamweaver for IDE.

Created a simple form.php page, POST action to process.php, pulls data from Oracle. Works fine (for my first php project). But when I edit the process.php file to try other techniques, I keep getting the older process.php versions results. Its not the browsers, I've tried with all types (IE, Chrome, Firefox).

I added the following to the head:
<?
//Set no caching
$ts = gmdate("D, d M Y H:i:s") . " GMT";
header("Expires: $ts");
header("Last-Modified: $ts");
header("Pragma: no-cache");
header("Cache-Control: no-cache, must-revalidate");
?>

On IIS server I added .php to Output Caching to NOT cache.

In php.ini I set oci8.statement_cache_size = 0

Still uses the first version of process.php. I've also created a new_process.php file and pointed POST to that file. But then I get "file cannot be found", even though its in the same folder as form.php. Although the next day if I try it agian, presto, its starts using the new_process.php file.

Running out of internet searches. Any clues??

Thanks
